Before and After conditional sleep

[nills3]

Hello.

I have a question. Is there any way of adding code after a conditional sleep?

What I am trying to do is quite simple; changing a boolean before attacking which would be the easy part, and then changing back the same boolean when the NPC is dead. I can achieve this, but it would result in spamming the change of the boolean. 

Thanks in advance if anyone can help me out.

This really isn't the purpose of a ConditionalSleep - it might help to copy/paste some pseudocode or the code itself that you're working with, so people can get a better idea of the question you're asking
